Definitions
- the present invention relates to a small form-factor pluggable (SFP) optic transceiver module for fiber channel applications and, more particularly, to an optical transceiver module cage of high data transfer rate program GBIC.
- SFP small form-factor pluggable
- Transceiver modules provide bi-directional transmission of data between an electrical interface and an optical data link.
- the module receives and converts electrically encoded data signals into optical signals which are then transmitted over the optical data link.
- the module receives and converts optically encoded data signals into electrical signals and transmit the electrical signals in the electrical interface.
- the transceiver module is mounted on a printed circuit board (PCB) assembly of a host computer, an input/output system, a peripheral device, or a switch.
- PCB printed circuit board
- a small form-factor pluggable module connects with a metal cage assembly mounted on the PCB.
- the metal cage allows both ease of interconnection and ease of installation on PCB.
- the cage functions to dissipate electrostatics and serves as an electromagnetic shield.
- the metal cage generally has two parallel sidewalls, a rectangular top, a rectangular bottom, and opposite ends.
- a conventional cage employs a two piece design.
- the two piece cage does not process a sufficient mechanical strength.
- the two piece design makes it difficult to manufacture and install the cage.
- the prior art cage forms legs for supporting the cage.
- no board locking mechanism is provided so that during the course of reflowing of a soldering process, the cage may inadvertently disengage from a PCB, causing poor soldering result.
- the present invention provides a small form-factor pluggable metal cage employing a one-piece design and the cage of the present invention has two types of legs.
- the first type is compliant legs that can be assembled through a board.
- the second type is piggy legs which does not go through the board.
- an object of the present invention is to provide a small form-factor pluggable metal cage having compliant legs, each defining an arc portion for preventing the cage from disengaging from a printed circuit board during the course of reflowing.
- It is further object of the present invention is to provide a small form-factor pluggable metal cage that enhances assembly.
- FIG. 1 is a perspective view of an optical transceiver cage constructed in accordance with the present invention
- FIG. 2 is a perspective view of the optical transceiver cage of the present invention in a partially opened condition
- FIG. 3 is similar to FIG. 1 with a portion of the cage removed;
- FIG. 4 is another perspective view of FIG. 2;
- FIG. 5 is perspective view of FIG. 1;
- FIG. 6 is an enlarged view of encircled portion VI of FIG. 5 showing legs of the cage of the present invention.
- FIG. 7 is a side elevational view of a portion of a sidewall of the cage constructed in accordance with the present invention.
- a small fact pluggable metal cage 1 in accordance with the present invention comprises a first sidewall 2 a , a second sidewall 2 b , a sidewall cover 3 , a top plate 4 , a soleplate 5 , a rear cover including an outer panel 6 and an inner panel 7 and two bulge patches 8 a and 8 b which are made of a single piece of blank material, such as a metal plate.
- the one-piece structure adds additional strength stability as compared with a prior art two piece metal cage.
- Each of the sidewalls 2 a and 2 b forms two spring tabs 24 a , 24 b proximate a front end thereof and a plurality of compliant legs 22 and piggy legs 23 at a lower edge thereof.
- the first sidewall 2 a also forms a plurality of resilient clasps 21 .
- a small notch 25 is defined in a rear edge of the first sidewall 2 a (FIG. 4 ).
- each piggy leg 23 comprises an elongate body 232 having a rounded end 231 .
- Each compliant leg 22 comprises an arcuate body 222 having a rounded end 221 substantially co-planar with the corresponding sidewall 2 a , 2 b whereby the rounded end 221 is offset with respect to a reference line in a first direction. The rounded end 221 is expanded so that it extends laterally beyond the body 222 in a second direction opposite to the first direction.
- the arcuate end 221 once engaging the corresponding hole of the PCB, help preventing the cage 1 from disengaging from the PCB during the course of reflowing.
- three compliant legs 22 are formed on each sidewall 2 a , 2 b and there are six compliant legs 22 in total among which three are offset in a direction away from the inner panel 7 of the rear cover of the cage 1 , while the remaining compliant legs 22 are offset in a direction toward the inner panel 7 of the rear cover of the cage 1 .
- the combination of compliant legs 22 offset in different directions enhances interferential engagement of the legs 22 with the corresponding holes of the PCB.
- the expanded ends 221 of the compliant legs 22 also serve as broad locks for securing the cage 1 on the board.
- the piggy legs 23 act as standoff separating the cage 1 from the PCB for enhancing soldering.
- the two types of legs make the metal cage 1 easy to connect to and install on a PCB.
- the top plate 4 forms spring tabs 41 at a front part thereof and defines a plurality of holes 42 at a rear portion.
- the sidewall cover 3 extends from the top plate 4 and overlaps the first sidewall 2 a .
- the sidewall cover 3 defines openings 31 , 32 for engaging the clasps 21 and the spring tab 24 a of the first sidewall 2 a , thereby securing the sidewall cover 3 to the first sidewall 2 a , forming a parallelepiped cage.
- the outer panel 6 of the rear cover extends from the top plate 4 .
- a rectangular hole 61 is defined in the outer panel 6 .
- the inner panel extends from the second sidewall 2 b has a free end. Legs 72 extend from a lower edge of the inner panel 7 .
- the inner panel 7 forms a resilient clasp 71 engaging the rectangular hole 61 of the outer panel 6 .
- a tab 73 extends from the free edge of inner panel 7 opposite to the second sidewall 2 b . The tab 73 engages the notch 25 of the first sidewall 2 a , thus securing the first sidewall 2 a and the outer panel 6 together.
- Patches 8 a and 8 b respectively extend from the first sidewall 2 a and the second sidewall 2 b are located above the inner panel 7 .
- the soleplate 5 is shorter than the top plate 4 and forms a central inward tab 52 and two grounding tabs 51 a and 51 b on opposite sides of the central tab 52 .
- a central leg 53 proximate the tab 52 and two legs 54 at a rear edge of the soleplate 5 extend from the soleplate 5 , also serving as standoffs.
